I usually go camping in other random places for about another week after BM. Pyramid Lake, Tahoe, Mammoth, and a lot of the spots we go to after the burn usually have burners rolling through. There definitely is something to be said for a good decomp phase before heading back to the city. We do it every year. I also like the feeling of knowing that when BM is over, our trip isn't even halfway done.
For these reasons I want to start doing more volunteering for cleanup afterwards in the coming years. Or maybe get into DPW or something. Fuckin love those guys.
